    摘要: Circuitry is provided that closely emulates biological neural responses. Two astable multivibrator circuits (AMCs), each including a negative differential resistance device, are coupled in series-circuit relationship. Each AMC is characterized by a distinct voltage-dependant time constant. The circuitry exhibits oscillations in electrical current when subjected to a voltage equal to or greater than a threshold value. Various oscillating waveforms can be produced in accordance with voltages applied to the circuitry.

    摘要: A memcapacitor device includes a memcapacitive matrix interposed between a first electrode and a second electrode. The memcapacitive matrix includes deep level dopants having a first decay time constant and shallow level dopants having a second decay time constant. The second decay time constant is substantially shorter than the first decay time constant. The capacitance of the memcapacitor device depends upon an initial voltage applied across the memcapacitive matrix and a time dependent change in capacitance of the memcapacitor device depends upon the first decay time constant. A method for forming a memcapacitive device is also provided.

    摘要: A memristive junction (400) can comprise a first electrode (102) and second electrode (104), with a memristive region (106) situated between them. The memristive region is configured to switch between two activation states via a switching voltage (118) applied between the electrodes. The activation state can be ascertained by application of a reading voltage between the first electrode and second electrode. The junction further comprises a rectifier region situated at an interface (420) between the first electrode and the memristive region, and comprising a layer (402) of temperature-responsive transition material that is substantially conductive at the switching voltage and substantially resistive at the reading voltage.
